python - 在 Django 中添加路径以创建更多 View

Question

我正在关注tutorial在 Django 网站上。我尝试复制这个:

我的代码如下:

View .py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render

# Create your views here.
from django.http import HttpResponse


def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

def detail(request, film_id):
    return HttpResponse("You're looking at film %s." % film_id)

def results(request, film_id):
    response = "You're looking at the results of film %s."
    return HttpResponse(response % question_id)

def vote(request, film_id):
    return HttpResponse("You're commenting on film %s." % film_id)

电影/urls.py

from django.conf.urls import url
from django.urls import path
from . import views

urlpatterns = [
    # url(r'^$', views.index, name='index'),
    # ex: /polls/
    path('', views.index, name='index'),
    # ex: /films/5/
    path('<int:film_id>/', views.detail, name='detail'),
    # ex: /films/5/results/
    path('<int:film_id>/results/', views.results, name='results'),
    # ex: /films/5/vote/
    path('<int:film_id>/vote/', views.vote, name='vote'),
]

这样我就收到了 ERR_CONNECTION_REFUSED 消息。如果我注释掉所有路径，仅留下索引 url，并注释掉 from django.urls import path ，则会显示一个页面，但这就是我在尝试添加更多 View 之前所在的位置。

您指的是较新 Django 版本的文档，因为旧版本中不存在 path() 。您可以通过点击右下角的文档版本按钮来选择文档版本here .
